CLEVIS.

Specification of Letters Patent.

Patented May 9, 1911.

Application led June 3, 1910. Serial No. 564,827.

To all whom it may concern:

Be it known that I, ERNEST PRECHEL, a citizen of the United States,residing at l/Voodlake, in the county of Yellow Medicine and State ofMinnesota, have invented new and useful Improvements in Clevises, ofwhich the following is a specification.

This invention relates to clevises and the object of the invention is toprovide asimple, cheaply constructed and etlicient clevis and to providean easily operated and elficient pin holder therefor.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawing whichforms a part of this application, and in which:

Figure l is a side elevation. Fig. 2 is a section taken on the line 2 2of Fig. 1 looking in the direct-ion of the arrow. Fig. 3 is a detailperspective view of the pin latch removed from the clevis. Fig. 4 is adetail perspective view of the pin.

Referring more particularly to the drawing l represents a yoke-shapedmember of the clevis which has its legs 2 provided at their ends withregistering apertures 3 adapted to receive the pin 4. This pin isnotched in its lower end and is adapted to be engaged by the locking arm5 which is piv-` oted at 6 to one leg of the yoke member 1 and extendsrearwardly thereon where it is provided with straddling flanges 7 and anoffset thumb piece S for operating the same. The latching or lockingmember 5 is constructed of a single piece of metal having its pinengaging end beveled as at 9 and having a thickness of approximatelyone-eighth of an inch. The body of the latching member is tapered fromits pin engaging end to its opposite end so that the flanges and thethumb piece 8 have a thickness of approximately one-sixteenth of an inchor one-half the thickness of the latch engaging end thus permitting therear end of the latching device to be sufficiently resilient so that theflanges may be engaged and disconnected from the sides of the leg 2.When the latching device is in locking position, the flanges 7 straddlethe leg and the beveled end9is in engagement with the notch in the lowerend of the pin 4, thus it will be seen that the latching device cannotbecome disengaged from the leg and that the pin is held in place in theapertures 3 until the latching device is disconnected from the leg byspringing the iiange 7 away from the leg and turning the device upon thepin 6. The bolt 4 is provided with an enlarged head 10 which overlapsthe sides of the leg 2 so that it may be readily grasped for removalfrom the apertures.

Having thus described the invention, what is claimed is A cleviscomprising a yoke-shaped member having apertures in its ends, a headedpin passing through said apertures and having a notch at one end, alocking member for said pin comprising a tapering body having a thinspring end, parallel inclined ianges bent up from said thin spring endat right angles to the plane of the body and adapted to engage onopposite sides of one leg of the yoke member, a thumb engaging lug bentup from the thin end for disengaging the flangesfrom the sides of theyoke member, a pivoting bolt passing through the locking member and oneleg of the yoke member for pivotally mounting the locking member, and athick diagonally cut notch engaging end held in engagement with thenotch of the pin by said flanges.

In testimony whereof I afliX my signature in presence of two witnesses.
